Weather in August
Temperature
Arcadia's warmest weather arrives in August, when temperatures average a high of 88.2°F (31.2°C) and a low of 64.8°F (18.2°C).Heat index
August's heat index is evaluated at a hot 91.4°F (33°C). Take more caution, heat exhaustion and heat cramps may occur. Long-lasting activity may cause heatstroke.The heat index's values are generally associated with conditions in shade and light breezes. The presence of direct sunlight can raise the heat index values by up to 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'feels like', is an amalgamation of air temperature and humidity to express the equivalent perceived temperature. This effect is personal, shaped by the individual's physical activity and heat sensitivity, influenced by factors including wind, clothing, and metabolic variances. Being under direct sunshine can magnify the heat experience, possibly pushing up the heat index by 15 Fahrenheit (8 Celsius) degrees. Heat index values are quite important for babies and toddlers. Young people are generally more susceptible than adults because they perspire less. Furthermore, their proportionally larger skin surface to their petite bodies and the increased heat output from their actions add to the risk.
